Levels of activity and enjoyment were measured in 73 Hong Kong primary school children (39 girls and 34 boys), during regularly scheduled physical education (PE) classes. Classroom activities were classified into one of 4 types (ball games, athletics, gymnastics and free play). Activity levels were monitored by heart rate telemetry and by direct observation (CARS), whilst enjoyment was scored using a 5-point Likert scale. Results showed that the average PE class used 22 minutes of the scheduled 35 class time, whilst the students spent 3.7 min in moderate-to-vigorous (MVPA) activity (60-90%HRR), and nearly 50% of the children spent less than 2 minutes with their heart rate above 159 beats · min⁻¹. There were no significant differences in activity levels between genders. Ball games and free play generally produced statistically higher heart rates and CARS values than gymnastics. The levels of enjoyment were low (3.7 − 1.0), but did not vary significantly between gender or activity type. A variety of social and environmental factors may contribute to these low activity and enjoyment levels.

The school has been identified as a key setting to promote physical activity. The purpose of this study was to evaluate the effect of a classroom-based activity break on in-school step counts of primary school children. Data for 90 children (49 boys, 41 girls, 9.3 ± 1.4 years) from three Irish primary schools is presented. In each school one class was randomly assigned as the intervention group and another as controls. Children’s step counts were measured for five consecutive days during school hours at baseline and follow-up. Teachers of the intervention classes led a 10 min activity break in the classroom each day (Bizzy Break!). Mean daily in-school steps for the intervention at baseline and follow-up were 5351 and 5054. Corresponding values for the control group were 5469 and 4246. There was a significant difference in the change in daily steps from baseline to follow-up between groups (p < .05). There was no evidence that girls and boys responded differently to the intervention (p > .05). Children participating in a daily 10 min classroom-based activity break undertake more physical activity during school hours than controls.

Physical activity patterns of Singapore school children aged 9–10 years were assessed by continuous heart rate monitoring. Fifty boys and 64 girls were monitored for three 14-hour periods during normal school days. In addition, 43 boys and 53 girls were monitored for 14 hours on a Saturday. Only 13 children (11.4%) experienced a daily 10-min period of continuous activity at a heart rate ≥140 bpm. Twenty percent of the boys and more than 50% of the girls never achieved a single 10-minute period ≥140 bpm. Boys achieved more periods of moderately intense activity (p < .01) than girls on weekdays. Lean girls were more active (p < .05) than the obese girls during weekdays. No differences were detected between activity levels on weekdays or on Saturday. The results indicate that Singapore school children in general rarely experience the quantity or quality of physical activity needed for maintenance and development of cardiovascular health and cardiopulmonary fitness.

This article is a contribution to the experience of testing motor fitness and exploring the EUROFIT test in young children. In the age group 5–7 years, the motor fitness tests showed strong dependency on age and a small dependence on sex. Body weight and height did not appear to have any impact on the test variables for this age group. The reliability test showed significant difference between test and retest in the plate tapping test only. The reproducibility was low in bent arm hang and flamingo balance, with coefficients of variation of 67%. Modest validity of the flamingo balance test and the standing broad jump test was confirmed with correlations of 0.43 and 0.52, respectively, by laboratory testing on a force platform. Factor analyses extracted 3 components, which explained 62% of the total variance, but no single component could explain general motor fitness. The EUROFIT Motor Fitness Test appeared to be applicable also in young children, but the reproducibility of two test items was questionable. Modification of test items was suggested to fit this age group.

The goal of this study was to determine the effect of nutrition education combined with sessions of vigorous extracurricular physical activity (VEPA) on the improvement of health related parameters in children in primary education. The sample group consisted of 54 children in the fifth year of primary education divided into two groups: an intervention group (IG) of 25 students and a control group (CG) of 29 students. The intervention lasted 7 weeks and consisted of 13 sessions of VEPA combined with sessions of nutritional education that were attended by the students in the IG as well as their parents. During the intervention the IG showed a decrease in the body fat percentage, total cholesterol, cholesterol linked to low-density lipoproteins and blood pressure, together with an increase in cholesterol linked to high-density lipoproteins, and an improvement in the maximum oxygen uptake and dietary intake profile compared with the CG, which showed an increase in the percentage of fats and no significant changes (p < .05) in other parameters. The results of this study provide evidence that a 7-week program of nutritional education and vigorous short-duration physical activity can improve health related parameters in children.

Purpose: To assess the association between the amount of recess provision and children’s accelerometer-measured physical activity (PA) levels. Methods: Parents/guardians of 6- to 11-year-olds (n = 451) in the 2012 National Youth Fitness Survey reported recess provision, categorized as low (10–15 min; 31.9%), medium (16–30 min; 48.0%), or high (>30 min; 20.1%). Children wore a wrist-worn accelerometer for 7 days to estimate time spent sedentary, in light PA, and in moderate to vigorous PA using 2 different cut points for either activity counts or raw acceleration. Outcomes were compared between levels of recess provision while adjusting for covariates and the survey’s multistage, probability sampling design. Results: Children with high recess provision spent less time sedentary, irrespective of type of day (week vs weekend) and engaged in more light or moderate to vigorous PA on weekdays than those with low recess provision. The magnitude and statistical significance of effects differed based on the cut points used to classify PA (eg, 4.7 vs 11.9 additional min·d⁻¹ of moderate to vigorous PA). Conclusions: Providing children with >30 minutes of daily recess, which exceeds current recommendations of ≥20 minutes, is associated with more favorable PA levels and not just on school days. Identifying the optimal method for analyzing wrist-worn accelerometer data could clarify the magnitude of this effect.

Advocates of quality daily physical education for prepubescent children frequently encounter the argument that such initiatives will harm academic progress. The impact of daily physical education upon the academic performance of primary school students is thus reviewed with particular reference to studies conducted in Vanves (France), Australia, and Trois Rivières (Québec). When a substantial proportion of curricular time (14–26%) is allocated to physical activity, learning seems to proceed more rapidly per unit of classroom time, so that academic performance matches, and may even exceed, that of control students. Children receiving additional physical education show an acceleration of their psychomotor development, and this could provide a mechanism for accelerated learning of academic skills. Other potential mechanisms include increased cerebral blood flow, greater arousal, changes in hormone levels, enhanced nutrient intake, changes in body build, and increased self esteem. Academic teachers may also favor the enhanced physical education program, creating “halo” effects, and the resulting release time may enhance their academic teaching. Irrespective of mechanisms, the implication for public policy is that daily required physical education can be introduced when a child enters primary school without compromising academic development. Given the importance of establishing positive health habits from an early age, school boards should be encouraged to follow a policy of required daily physical activity in primary schools. Evidence of specific benefit in students with learning disabilities remains less convincing.
